Resumen
Plants commonly interact with microorganisms that may influence their physiology and performance. Epiphytic yeasts are microorganisms that can be found in the phylosphere, in significantly larger numbers in fruits than in other plant tissues due to their higher nutritional content. The present study aimed to contribute to knowledge of epiphytic yeasts associated with Eugenia dysenterica DC. fruits and to evaluate their antimicrobial activity against phytopathogens. E. dysenterica fruits were collected, washed in saline solution, and sonicated. Each fruit solution was plated in three Petri dish

Resumen
Incorporating beneficial microorganisms in crop production is the most promising strategy for maintaining agricultural productivity and reducing the use of inorganic fertilizers, herbicides, and pesticides. Numerous microorganisms have been described in the literature as biological control agents for pests and diseases, although some have not yet been commercialised due to their lack of viability or efficacy in different crops. Paecilomyces is a cosmopolitan fungus that is mainly known for its nematophagous capacity, but it has also been reported as an insect parasite and biological control ag

Antagonistic bacteria contribute to the management of plant diseases by stimulating the natural defenses in the host and/or by ensuring direct biocontrol of the aggressors. The objective of this work was to isolate, identify and evaluate (in vitro) various Bacillus spp. for their potential to control phyopathogenic fungi. Selection of the 40 strains of Bacillus previously isolated from the soil in various areas of western Algeria was carried out by direct confrontation on the mycelial growth of four phytopathogens (Fusariumoxysporumf.splycopersici, Alternaria tenuis , Phytophthorainfestans, As

Trichoderma fungi are promising candidates for biocontrol agents and plant growth promoters. Trichoderma atrobrunneum and T. simmonsii were evaluated for the control of soil-borne phytopathogenic fungi, in the present study. Dual culture tests with Rhizoctonia solani and Fusarium oxysporum f. sp. lycopersici were used to conduct in vitro evaluation. In the presence of Trichoderma, phytopathogen’s growth rate was inhibited up to 59.70% for R. solani and 42.57% for F. oxysporum.

Resumen
Yield loss through harmful fungi is a serious problem in crop production worldwide. Cereal residues like straw are frequently infected by Fusarium fungi, which produce mycotoxins like deoxynivalenol (DON). Mycotoxins lead to quality losses in cereal-based food and feed which endangers human and animal health. Especially under conservation tillage, when mulching techniques are applied to protect soil from erosion, run-off etc., residues should be efficiently degraded to protect the currently cultivated crop from fungal infection and mycotoxin contamination.

Plant diseases cause losses of approximately 16% globally. Thus, management measures must be implemented to mitigate losses and guarantee food production. In addition to traditional management measures, induced resistance and biological control have gained ground in agriculture due to their enormous potential. Endophytic fungi internally colonize plant tissues and have the potential to act as control agents, such as biological agents or elicitors in the process of induced resistance and in attenuating abiotic stresses.

Resumen
Potato common scab causes significant economic losses worldwide, and current control methods remain ineffective. However, biological control methods have been effective in controlling phytopathogens in several other crops. Trichoderma spp. and Bacillus subtilis are the most studied microorganisms in agriculture for controlling plant diseases. However, interactions between these biological control agents and the organic matter present at the cultivation site have not been extensively studied. Therefore, the objective of this study was to evaluate the action of biological agents in controlling p

In the agricultural context, several strains of Pantoea spp. can promote plant growth through direct or indirect mechanisms. Members of this genus contribute to plant growth mainly by increasing the supply of nitrogen, solubilizing ammonia and inorganic phosphate, and producing phytohormones (e.g., auxins).

Disposal of post-harvest residues from agro-ecosystem remains one of the urgent issues of today for agricultural producers. Burning straw and stubble is an extremely radical and destructive method for biogeocenosis, because during combustion between straw and the soil layer due to water vapor, conditions are created that the burning temperature exceeds 600°С. As a result of such actions, microorganisms, worms, insects, small vertebrates die and the fertile layer of humus is destroyed.
